I agree whole hearted with Shaun. I have been backflusing with Cafiza, weekly,for years with no adverse effects to my machine. Conversely, I notice an immediate improvement to the taste of my shots after back flushing. The taste slowly and imperceptibly diminishes over the course of a week. But then again improves after backflushing. Furthermore, grinders tend to build up rancid oils and should be cleaned monthly. I vacuum it out.Clean the burrs with a denture brush and then run some Minute Rice through the grinder. I grind 1/3 of the rice at a time and let it sit in the machine for 5 minutes after grinding. Then I repeat the cleaning protocol again. Immediate improvement in the shots is also noted. On Tue, Jan 12, 2010 at 6:22 AM, Shaun Taylor <[email protected]> wrote:
